From March 3–5, senior brand marketers will gather at the SLS Baha Mar in Nassau for a different kind of advertising event. While much of the industry conversation continues to orbit around AI headlines and retail media land grabs, The Outcome Summit - hosted by Attain - focuses on improving what actually drives sales.
The private summit convenes decision-makers who are already recalibrating 2026 and 2027 budgets around deterministic purchase data and verified sales lift. For many brands, the era of proxy metrics and attribution theater is giving way to accountability, executive scrutiny, and hard revenue questions.
A featured highlight of the summit will be a fireside conversation between award-winning actor, producer, and entrepreneur Anthony Anderson and Attain CEO Brian Mandelbaum. Their discussion will explore how entertainment, influence, and measurable commerce are converging, and what that convergence means for brands navigating an increasingly performance-driven environment. Anderson’s participation reflects a broader shift happening across the creator and entertainment ecosystem: Influence is increasingly tied to commerce outcomes.
Creators Rebecca Zamolo and Matt Slays - whose combined reach spans tens of millions across YouTube and social platforms - will also be at the Outcome Summit thanks to their partners, Influential. Their participation signals the next phase of the creator economy: revenue accountability. As marketers face mounting pressure to justify spend, creators are becoming more integrated into performance strategies that connect content exposure to verified purchase behavior.
Several themes are expected to dominate the three-day agenda:
- Real-time sales measurement and signal capture
- Retail media accountability amid fragmentation
- The continued decline of last-click attribution
- AI’s evolving role in identifying actionable signals
- Compensation models tied directly to measurable outcomes
Attendees will explore how today’s media ecosystem is being reshaped by broader structural forces - from the evolving role of AI and data quality challenges to the increasing need for cross-functional alignment between media, analytics, finance, and creative teams. Brands and agencies alike are looking to forge greater clarity around impact versus impression, proof versus promise, and investment versus return, reflecting a collective push toward measurement strategies that hold up under real scrutiny and deliver confident planning for 2026 and beyond.
Attain intends the Outcome Summit to be a laboratory for shared problem-solving and a forum where senior decision-makers can sharpen their thinking, challenge assumptions and forge the collaborative relationships that will shape the next phase of performance marketing. Whether confronting measurement fatigue, adapting to new commerce dynamics, or aligning teams around outcomes that matter, the insights emerging from Nassau will help illuminate a path forward for leaders seeking to move toward accountable growth.
